Radio Shack Brings Back iPhone Trade-In Deals, Unveils Foursquare Offers

It’s official, Radio Shack has revived their iPhone trade-in deals while adding check-in offers for Foursquare users.

Under the current plan iPhone 3G and 3GS devices in good condition will earn customers $75 credit towards any iPhone available in-store. Under the plan a trade-in brings the price of the iPhone 4 down to $125 or $225 depending on which unit (16GB or 32GB) is chosen.

Trade in your iPhone and pick up the 8GB iPhone 3GS and you’ll not only get the phone for free, but Radio Shack will throw in a $25 gift card.

The trade-in program begins on Friday and runs through April 11.

Users willing to check-in on Foursquare or Google Places will also be able to receive 10 to 20 percent off non-Apple devices.
